MACHINE FOR SETTING TIRES.

SPECIFICATION forming part of Letters Patent No. 444,175, dated. January 6, 1891.

Application filed November 9, 1839. Serial No. 329,793. (No model.)

To all whom it may concern.-

Be it known that I, JONATHAN B. W'EST, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in a Machine for Setting Tires, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention relates to a machine for setting metal bands upon thehubs of wheels and similar articles, and also tires upon wheels, the bands and tires being first put to place upon the wood-work in a cold state. The metal is then compressed or upset by direct radial pressure from without, causing the bands to assume smaller diameters, and so tightly pinch or compress the wood-work within them. i

The invention consists in constructing and arranging the parts of the machine so as to more easily and better compress the bands or tires than has heretofore been done, causing them to be set more firmly upon the wood-work.

The invention is hereinafter more fully described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan of the upper or supporting plate of the machine with parts omitted; Fig. 2,a plan of the lower parts of the machine with part-s broken away and omitted, the levers and posts being horizontally sectioned, as on the dotted line acwin Figs. 3 and-4; Fig. 3, a side elevation of parts of the machine, parts being vertically sectioned, as 011 the dotted line y y in Fig. 2 Fig. 4, a similar view of some of the upper parts of the machine, parts being sectioned, as on the dotted line zzin Fig. 1, parts being broken away and other parts shown in two positions by full and' dotted lines. Fig. 5, drawn to a larger scale, shows the under surface or parts of two of the compressingjaws with associated pieces, parts being broken away; Fig. 6, a side elevation of the parts shown in Fig. 5, viewed as indicated by the arrow 00 in the latter figure; and Fig. 7, another form of the compressing-jaws.

Referring to the parts shown in the drawings, Ais ahorizontal circular bed-plate, supporting at its center a concentric operatingcylinder B.

O is a middle horizontal plate formed in three radial arms resting upon standards D, secured to the bed-plate, the function of the middle plate being mainly to guide the rod 6 of the cylinder B.

E are posts rising from the plate 0, which support the upper-horizontal annular plate F. Upon this upper plate is arranged a series of radial compressing-jaws G, equally spaced, resting upon seats don the plate and between small projecting guides 1". These jaws are driven toward the center or axis of the plate F by a powerful pressure, hereinafter explained, to compress the metal bands I), Fig. 1, upon the hub or wooden center piece H, shown in horizontal section. Each jaw is directly actuated by a pendent lever c, resting in bearings d in the plate F, Figs. land 4, the head o of the lever reaching upward into a cavity 13 in the jaw.

The cylinder 13 is substantially of common construction, provided with the usual internal piston I, Fig. 2, and driving-rod e, rigid with the piston, thelatter being actuated by steam, compressed air, water, or other means usual, and in substantially the usual manner.

K is a circular head made rigid with the driving-rod e above the plate 0, consisting of two similar plates f and g, and formed with radial cavities h, which constitute rests for the inner ends of connecting-bars L, joined, respectively, to the lower ends of the compressing-levers c by bolts 2'. The connectingbars are provided with short cross-pins a, resting in an annular groove'l, formed in the plates f and g, Figs. 2 and 3, which pins serve to hold the said bars in place in the head K. Now it will be seen by observing Fig. 4 that when the piston or the driving-rod e is carried downward by any pressure or force the connecting-bars L, which are in an' inclined position, will be brought toward a horizontal position,v as shown by dotted lines, acting powerfully against the lower ends of the respective levers c to push them outward. This will cause each of the compressing-jaws G to be moved through a short distance with great power toward the center of the machine and bear upon the band I), which latter is thus compressed into a smaller diameter and caused to firmly press the wood H, Fig. 1. The levers occupy rectangular vertical openings 76, Fig. 4, in the plate F within the respeetive seats u for the jaws. The jaws are l formed with parts I, Figs. 1 and 4, extending downward through rectangular openings 11 in the plate and provided with bolts 0, and also with washers p on theunder side of theplate 1 Thus constructed the jaws are prevented 1 from being lifted oil their seats, while they r are permitted to freely move endwise on the respective seats a. i

To compress rings or bands of smaller diamcter, I employ a series of steel sectors or bushings rat the ends of the respective jaws, Figs. 5 and 6. These sectors decrease in width as they approach the center, as shown, 5 and are held by supporting-tingers .s, clamped f to the under surfaces of the respective jaws by means of clamping-plates t and screws u. (Sce, a1so, Fig. 1.) These sectors are formed 1 at their lower ends with reduced parts,which enterthe space between the opposingfingers, j as shown. More or fewer of these sectors are used in any given case, this depending upon the diameter of the band to be compressed, the fingers 3 being adjusted endwise to positions to correspond with the number of seci tors used.

For compressing-bands of larger diameter I employ longer jaws, provided with shoulders a or (L as shown in Fig. 7. These jaws are operated by the levers c in the same mannor as the short jaws shown in the other figures are operated, and fit the same seats a. They are adapted to set the tires of wheelbarrow-wheelsforinstance, as shown at b' or the tires of carriage-wheels. (Shown at c'.) When the jaws are made long to set carriagewheel tires, the plate F is formed with extensions d to support the outer ends of the jaws.

The plate 1 is formed with a central opening 6', so that the hub of the wheel may extend down through the same, if necessary, while the band or tire is being set. In case a band is to be set upon the middle part of the hub I employ holders R for the band, Figs. 1 and 8. These holders are pivoted on standards f, rigid with the plate F, so as to move in vertical planes. The holders each consist of a thin blade of steel 9, held adjustably by arms 7t, substantially in a horizontal position. These blades extend forward from between adjacent jaws and receive upon their extreme ends the band to be set upon the hub, the latter extending downward through the opening e. The holding-blades are made vertically adjustable by means of thu mb-screws '1 and the blades are unclamped or loosened to be adjusted horizontally by thumb-screws is.

It is plain that; the drivinga'ode maybe operated by a screw instead of a piston wltln in a cylinder, as shown, should it not be convenient to employ a cylinder and piston at any time.

hat I claim as my invention is 1. In a tiresetting machine, a supporting plate and a series of compressing-jaws arranged in a circle and held to move in radial hearings on the plate inwardly against the tire, the inner end of the jaws forming substantially a continuous circle, in combination with driving-levers for the jaws beneath the plate arranged in a circle, and a verticallymoving driving-head for the levers beneath the plate and surrounded by the levers, the plane of the driving-head being between the plane of the jaws and the plane of the lower ends of the lovers, substantially as shown.

9. In a machine for setting bands and tires, a supporting-plate, in combination with aws held to move radially thereon, lovers to move the jaws, a driving-rod, a head upon thedriving-rod, connecting-bars joining said head and levers, supporting-fingers secured to the jaws, and sectors held by said fingers, substantially as and for the purpose set forth.

In combination with the supportingplate F of a machine for setting metal tires or bands, adjustable supports for the bands, compressing-jaws held by said plate, levers to operate the jaws, an operating-cyltndcr for the levers, and connections, substantially as shown and described, for said cylinder and levers.

4:. In a machine [or setting tires, a supporting-plate, and a series of compressingjaws arranged in a circle on the plate and held to move in radial directions inwardly against the tire, the inner ends of the aws forming substantially a continuous circle, in combination with levers to move the jaws arranged in a circle beneath the plate, a powercylinder having a non-rotating axial rod within the circle of levers beneath the plate, a head rigid with the rod, and connectingbars for the head and the respective levers, substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand, this 6th day of November, 1889, in the presence of two subscribing witnesses.
